oxgoad writes "Sun Microsystems, Federal Express, the National Radio Astronomy Observatory -- what do they have in common? All have used, or are currently using, the programming language Forth in critical subsystems of their products or processes. 'What is this language Forth?' you ask. Forth has been called 'One of the best-kept secrets in the computing world.' Read on for a review of the book Forth Application Techniques authored by Elizabeth D. Rather." Forth Application Techniques author Elizabeth D. Rather pages 148 publisher Forth, Inc. rating 5 reviewer oxgoad ISBN 0966215613 summary A concise introduction to the Forth programming language.

Who & What

Elizabeth D. Rather, president of Forth, Inc., would appear to be the second Forth programmer in the universe. This distinction came about in 1971 when she was brought in at the Kitt Peak NRAO to maintain code written in a quirky language developed by Chuck Moore. Running on a DDP-116 and a H316, this code was responsible for controlling the telescope, data acquisition, and graphical display. After a few years, Moore and Rather, along with Edward K. Conklin, formed Forth, Inc. to attempt commercialization of the language.

Forth Application Techniques attempts to provide a comprehensive introduction to the language for the neophyte Forth programmer. I would say that it pretty much succeeds as such, quietly plodding away through each primitive and feature. It is written in workbook style with various sample problems for the reader to complete. You might not be a Forth coder after reading the book cover to cover; however, you will have a working knowledge of the language and should be able to walk through legacy code with a minimum of difficulty.

If I might step aside from my role as unbiased book observer for a moment, I would like to make a few comments about the state of programming languages in general. It seems that quite often we take for granted essential, but practically invisible, tradesmen such as plumbers and garbage collectors. (Fire your janitor and your web designer -- guess which one you will miss first. Guess which one will still be employable 15 years from now.) Yet, without their services, our daily quality of life would certainly fail to meet our expectations.

Likewise, Forth seems to be an invisible language. No flash, no e-commerce, and no glamour. Such is the nature of embedded systems -- even though every Federal Express delivery driver carries a Forth-based device on his belt. This appears to have resulted in a dearth of quality books dealing with Forth. Search your favorite online book retailer and note the dozens of Forth books that are no longer in print.

While Scheme is from the ivory tower and Forth might be said to be from the machine shop, they do have something in common that is a possible deterrent to the popularity of Forth. Like Scheme, you either get Forth -- or you don't. Stack-based languages leave some programmers dazed and confused. And, as with most languages, it is possible to write some truly obfuscated code. Any language that will allow you to define the number 4 as a word that places the number 3 on the stack can be a frightening weapon in the hands of the contrary.

Kudos

Forth Application Techniques can be commended on its consistency. Careful attention has been given to typefaces to distinguish interpreter output from user input. All primitives and defined words are covered in a clear and unambiguous manner. The book is spiral bound in a plastic binding, and this lay-flat binding is great when using it at your computer or while eating lunch.

Quibbles

The same lay-flat spiral binding that is such a boon when working at the computer can be somewhat of a nuisance when when attempting to hand-hold the book -- the book tends to flop about and feels very insubstantial.

While Forth Application Techniques is very complete and accurate, it is also extremely passionless. You might compare it to a biology textbook discussion of sexual reproduction with no mention of romance. There is no discussion or examples of using Forth in ways that will bring enlightenment. To be fair, in the preface it states that the purpose of the book is to support Forth classes taught at Forth, Inc. This is something that is not entirely clear when examining online retailers' display of the book.

Also of note is that there are occasional features specific to Forth Inc.'s SwiftForth product documented in the book. I would not consider this a real issue as all instances are clearly denoted with an icon. With the exception of chapter 9, which is entirely Forth Inc. specific, the readability is not affected in any way.

Crimes

Forth Application Techniques has no index. With its workbook styling, most will not consider this to be a tragedy. All the same, it would be convenient to look up primitives and defined words.

Conclusions

Should you buy this book? That depends on your desired end result. It is adequate for a quick introduction to Forth. If you are intending to write production code I believe Forth Programmer's Handbook (from the same publisher, review forthcoming) would be a better choice. If possible, I would supplement either with a used copy of Leo Brodie's Starting Forth -- an out-of-print classic.

Where I foresee this book to be a great benefit is in ordering a half-dozen copies for your programming team prior to taking on a legacy project or when considering Forth as a new development platform. The members of your team that "get it" can then enlighten the others with this invisible language.
